Wellcome Image Awards 2017: winners show the art of science

Award-winning entries include photos, 3D models and digital illustrations of scientific processes, and human and animal anatomy. The 22 winning images were chosen from all those acquired by the Wellcome Images picture library in the past year

This image shows how an ‘iris clip’, also known as an artificial intraocular lens (IOL), is fitted onto the eye. An iris clip is a small, thin lens made from silicone or acrylic material, and has plastic side supports, called haptics, to hold it in place

The Placenta Rainbow highlights differences in mouse placental development that can result from manipulation of the mother’s immune system. These placentas were investigated at day 12 of the 20-day gestation period – the point at which a mouse’s placenta has gained its characteristic shape but is still developing

MicroRNA scaffold cancer therapy: This therapy has already been tested in mouse models of breast cancer, where it caused a tumour to shrink by nearly 90 per cent after just two weeks

Unravelled DNA in a human lung cell: This picture shows the nucleus of one of two new daughter cells. The DNA in this cell has somehow become caught, and is being pulled between the two cells.

Blood vessels of the African grey parrot: This image shows a 3D reconstruction of an African grey parrot, post-euthanasia

Language pathways of the brain: The brain is composed of two types of matter. Grey matter contains cells, and is responsible for processing information. White matter connects these areas of grey matter, allowing information to be transferred between distant areas of the brain.

Zebrafish eye and neuromasts: This four-day-old zebrafish embryo has been modified using two mechanisms – borrowed from the fascinating worlds of bacteria and yeast – that are widely applied in genetics research

Ingrid Lekk and Steve Wilson, University College London

Rita Levi-Montalcini (1909–2012) was an Italian neurobiologist and the joint recipient of the 1986 Nobel Prize in Physiology or Medicine for the discovery of nerve growth factor (NGF)

Hawaiian bobtail squid: Native to the Pacific Ocean, Hawaiian bobtail squid are nocturnal predators that remain buried under the sand during the day and come out to hunt for shrimp near coral reefs at night

Mark R Smith, Macroscopic Solutions

Synthetic DNA channel transporting cargo across membranes: These DNA nanostructures are currently being engineered for use in vaccines, biofuels and biosensors, and as research tools

Hidden Learning is taken from Chrysalis, a project at the University of St Andrews designed to bring together women scientists at all stages of their careers to talk about issues and to seek advice and inspiration. The veil seen in this image is made up of the molecular structure of a sugar molecule, contributed by one of the participating scientists

Original painting by Sophie McKay Knight, with imagery contributed by women scientists from the University of St Andrews – part of the Chrysalis project coordinated by Mhairi Stewart

Brain-on-a-chip: Here, researchers are investigating how neural stem cells grow on a synthetic gel called PEG

These scenes are inspired by works by medieval artists and the 15th-century Dutch painter Hieronymus Bosch

Pigeon thermoregulation: All animals possess unique variations in their anatomy that help them adapt to their environment – this is how pigeons do it

Blood vessels (blue) can be seen radiating from the centre of the image, supplying the entire retinal surface. It was created by digitally stitching together over 400 images to form one large image, so as to show the entire surface of a mouse retina

A 3D model of a healthy mini-pig eye. The dent on the right-hand side of the image is the pupil, the opening that allows light into the eye

This image is part of a series called Stickman – The Vicissitudes of Crohn’s. Its images are based around the character Stickman, a proxy or alter ego of the artist, who suffers from Crohn’s disease
